Seat (Optional) - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

3.5.5.2

SEAT (OPTIONAL)

The seat is really comfortable, in fact it features six different
adjustment options:
- longitudinal position;
- back inclination;
- degree of suspension, in order to cushion the inevitable
vibrations and jumps as much as possible;
- height and cushion inclination;
- armrest position;
- rotation for works with the backhoe.
The operator can choose the driving position that is most suitable
for his physical structure and according to the angular adjustment
of the steering wheel.
The longitudinal adjustment of the seat can be carried out by
means of the lever (1), making the seat slide on the apposite
guides; once the desired position has been found, release the
lever and make small movements with the seat to make sure that
the retainer pin is correctly engaged in its seat.
The back can be adjusted by operating the levers (2) and at the
same time exerting pressure with the back; the back will
automatically adapt to the physical structure of the operator.
The degree of suspension can be adjusted by rotating the knob
(3) and checking the graduated scale on the knob itself.
The ideal position is reached when the weight indicated on the
scale corresponds to the operator's weight. In any case, the
operator can choose the degree of suspension at his sole
discretion.
Turn the knob (3) clockwise (⊕ ) ) to obtain a more rigid
suspension, or counterclockwise to obtain a softer suspension.
The inclination and the height of the cushion can be adjusted by
means of the levers (4).
To facilitate access to the seat, both armrests can be rotated and
positioned against the back.
The inclination of the armrests can be adjusted with the knobs (5)
that are positioned under the armrests.
The rotation of the seat for works with the backhoe is obtained by
operating the release lever (6); the locking is automatically carried
out every 180°.
The seat is equipped with a safety system that sends out
q
an acoustic alarm if the reversing gear control lever is
operated while the seat isn't in the correct frontal position.
